"I don't know what I would do without her," Roberts said. "She is great in every way." Roberts has spina bifida. She's confined to a wheel-chair. Roberts said her health took a turn for the worse about two years ago.

Roberts said she quickly realized that Quila was no ordinary Chihuahua.

"I dropped her bag of treats and I didn't expect her to pick it up, but I couldn't do it at the time," Roberts recalled. "I have this hand gesture of give it to me and she did."

It did not stop with the bag of treats. From dropped clothes in the laundry room to misplaced magazines and even shoes, Quila is a born go-getter.

"She'll try even if it is really, really big," Roberts said. "She gives me everything I need. Everything i need. ... Especially being in the condition I am, having chronic pain in my abdomen all the time, it's hard for me to bend over and hard for me to reach stuff."

Roberts said Quila seems to know exactly what she needs when she needs it. "She picks up my pill bottles and brings them to me. I mean sometimes that is really what I need."

But Quila provides more than just physical help.

"It's kind of neat because when I am in bed those days crying because of pain, or whatever, she is in bed with me and you can ask my mom, she cries with me," Roberts said.

While Quila is not your typical service dog, Roberts got her certified, feeling her little dog's heart and determination were plenty big enough for the job.

"I mean I'm in a wheel chair, so I really don't need a big dog," Roberts said. "She hands it to me anyways. It's OK; it works out."

Roberts said that's why she wanted to share her story -- and Quila's. She says no matter how bad things get, sometimes a little dog that does tricks, is just the trick to keep the pain at bay, keep a smile on your face, and keep you going every day.

"I never expected her to be this great," Roberts said. "But she is she is a good dog. "
